Time passed quickly, Chu Yang was silent in cultivation again, and he also received the jade card given to him by the Jade Spirit Heart, but he didn't plan to use it.

Now Chu Yang and Su Xuerou have two days off to improve their strength during the day. At night, after Su Xuerou fell asleep, Chu Yang entered the Chaos Bead Space to learn alchemy.

Lan Xiaoyue entered a state of retreat again, and Chu Yang did not disturb her, but crept into an empty room.

took out the Dan Furnace and placed it in front of him, and then Chu Yang took the Spirit Grass in turn according to the Dan Fang, fortunately, he went to the Luoshen Mountain Range this time and got a lot of Spirit Grass, so even if he kept failing, there were still many reserves of the Dan.

Chu Yang first ran the heart method every day, and after adjusting the breath, Chu Yang took out a medicinal herb and threw it into the Dan furnace, and then Chu Yang ran the spiritual energy transformation method, and the spiritual energy in his palm turned into a flame to wrap the Dan furnace.

The Dan furnace slowly floated into the air, driven by the high temperature, the medicinal materials began to slowly melt, and then turned into a pool of crystal liquid, Chu Yang continued to use the mental method to peel off the impurities in it.

For a long time, Chu Yang let out a long sigh of relief, after these many attempts, the speed at which he refined the medicinal materials became faster and faster, and the medicinal materials he refined became more and more refined, but it was still as laborious as before.

Every time he just refined the medicinal herbs, he almost consumed all his spiritual energy, so Chu Yang had to continue to take the Restoration Pill that Ouyang Ke had given him earlier while refining the pill.

If Ouyang Ke knew that the Restoration Pill he gave to Chu Yang to keep for backup during the battle was almost exhausted when he used it to learn alchemy, Ouyang Ke would definitely be so angry that he vomited blood......

"I didn't expect that alchemy was consumed so much, and the best of refining a furnace of pills was only twelve, Ouyang senior gave me so many pills, and I don't know how many recovery pills the alchemist consumed. Chu Yang thought in his heart.

After a while, Chu Yang retracted his mind, now that the medicinal materials were almost fused together, he was about to carry out the final step of the condensing pill!

After such a long time, he has also overcome one problem after another, but this Ning Dan has never been able to overcome it. It's been several times, and Chu Yang is sure that all the steps are seamless, but he just can't succeed in Ning Dan, resulting in the previous attempts falling short!

A little beads of sweat flowed from Chu Yang's forehead, he was still desperately urging the operation of the exercises, and the pills in the Dan furnace had also begun to take shape, and it could be completed if he persisted a little longer.

Not long after, a flat tire sound came: "Puff~"

"Alas~" Chu Yang sighed, he knew that this furnace of elixir had been scrapped again!

"What went wrong?" Chu Yang frowned and pondered: "Now I only have the last one left in the Restoration Pill, if I fail again, after I finish refining the pill, I will fail due to the lack of spiritual energy." ”

"What's the problem?" Saying that, Chu Yang stopped his gaze on the Dan furnace: "Could it be that this Dan furnace has not been used for too long, so it is broken?"

However, as soon as this speculation came out, Chu Yang shook his head and vetoed it, although this Dan furnace was old, he couldn't see the grade, but Chu Yang could feel that this Dan furnace was much higher than the grade of the absolute blade that Yu Lingxin had created for himself.

But also, what can be left in the storage ring by such a strong person, and what will be such an ordinary thing?

Chu Yang continued to think about and summarize the reasons for the failure, and finally he finally figured out what the problem was. That was the temperature of the fire, the temperature of the flame transformed by his aura was still a little lower, if the temperature was higher, he would be able to condense the pill successfully.

But he was already running the exercises at full strength, and the temperature was also pushed to the maximum, so what else could he do to increase the temperature of the flame?

Just when Chu Yang was at a loss, he suddenly remembered the Chaos Pill Duel in his mind, he hadn't tried it before, if he used the Chaos Dan Duel to refine the Dan, would it be improved?

Just do it, and then Chu Yang recalled the Chaos Dan Decision, and his mind activated his mind to mobilize his aura.

Time passed, Chu Yang's brows were deeply locked, this Chaos Pill is by no means that simple, Chu Yang also knew after cultivating for a while, after cultivating the entire mental method, he could directly transform the aura into flames, and if he used this Pill Decision to refine the Dan, the success rate and the quality of the pill would also be greatly improved.

It's just that this last step of spiritual qi turning fire is difficult to do, and Chu Yang's attempts again and again have ended in failure.

"Whew~" Chu Yang exhaled a long breath, and then he ran the Chaos Pill Decision again, although he failed many times, but he was not discouraged, but tried again and again, looking for the problem.

"Peng~" A slight explosion came, and then a raging flame rose from Chu Yang's palm.

Chu Yang's eyes were a little hot, he had already sensed the incomparably hot heat inside the flames, Chu Yang had a whim, if he summoned such a ball of extremely hot flames to attack during the battle, would there be any unexpected results?

However, these are not things that Chu Yang should consider at the moment, since he has successfully summoned the Danhuo, then Chu Yang will try to refine the Dan again.

Chu Yang threw the spirit grass into the Dan furnace without hesitation, and then he ran the Dan Decision, and the raging flames swept towards the Dan furnace.

After a while, Chu Yang had a happy expression on his face, if he used Danhuo to refine medicinal materials, not only would the speed increase several times, but even the purity of the medicinal materials would be higher!

"This time it will be successful. Chu Yang said with a chuckle.

It didn't take long for all the medicinal materials to be refined, and Chu Yang found that the spiritual energy he had lost was only one-tenth of what he had before!

At this moment, Chu Yang understood, where is the alchemy that needs to consume a large amount of recovery pills, everything is just that he got the wrong method and took the wrong path......

However, the previous failure was not a meaningless thing, because Chu Yang had already figured out all kinds of processes and various matters clearly, so this time in alchemy, his progress was fast, and everything was just a matter of course.

It was time for the Ning Dan again, the medicinal liquids were fused together under Chu Yang's control, and as the Dan Fire baked, the moisture in it began to flow, leaving only the strongest part of the medicinal power.

Chu Yang closed his eyes, his mind was still observing the inside of the Dan furnace, although he only saw a vague approximation. However, Chu Yang also saw that the large balls of medicinal liquid began to slowly separate, and finally condensed into small pills.

"Knot!" Chu Yang let out a deep sigh, the temperature of the flame rose again, and success or failure was in one fell swoop.

After a while, a burst of refreshing medicinal fragrance came, and Chu Yang also had a happy smile on his face, Dan Cheng!

Chu Yang put away the Dan fire, and then he couldn't wait to open the Dan furnace. The twelve dark red pills lay quietly inside, and Chu Yang checked the color, which was actually much better than the color of the bottles of Ning Yuan Pill that Ouyang Ke gave him.
